Hello, I have a 360 mm watercoolling 3 years old. I don't want buy another for switch to the z690 motherboard. What's i need? The retrofit? ELITE Series Retention Kit? Because i don't see my ref in the list of compatibility....It's strange since not so old. For exemple i have a nzxt watercoolling who have 8 years and they have one compatible and free... Thx in advance.
